SHOE FORMER.

Appiieaaofi fiidoctober 10, ma 'seria No. 742,835.

Thisinvention relates to shoe' formers and particularly to those shoe formers which are expansible in the forward part of the shoe.

'The primary object ofmy invention is the provision of an improved 'shoe former. l

Another object of my invention is the pro- Vision of a shoe former having an expansible means .Operating both to the right and to the left from the longitudinal axis of the former.

Another and further object of my invention is the provisionv of a shoe `former comprising an expanding means having` a com- .bined sliding and pivoted movement.

Another and still fnrther object of my inv-ention is the provision of an limproved shoe former having an expansible means for complementary portions at the forward end thereof, the eXpa-nsible means comprising Superimposed plates lpivoted together and |to the Vrespective complementary portions and having` converging slots .thereim the villustrated Va preferred embodiment ofv my invention,

F-ig. 1 is a plan view of the Operating niechanism of my invention,,s`howing the parts contracted.

Fig. V2 is 'a plan view similar toy Fig; 1, 'but showing the vparts eXpanded.

Fig. 3 is a side elevational view.

Fig. 4 is a detail cross sectional view on :the line '1-4- of Fig. 2.

IThe same reference characters refer to the --same or similar parts thronghont the several Views.

The nnmerals 10, 10a. designate the forward complementary portions of the shoe former vwhich act. when expanded, to preserve the shoe in its proper Shape. At 11 'is the heel portion of the former' vforV engaging' the inner rear portionof the shoe when the former is in place.

The complementary` portions are slotted on their inner sides to permit entry of the plates 12, there being one for each complementary portion. These 'plates 12 are of -tapered shape and each has an eXtending portion 13 in which is located the pivotbear- 'ang for pivots 14 which may be in the forrn of nails driven into the complementaijy portions as shown. It is to be noted that there is a space at each side 'of the extending portions. This permit-s of a pivotal movement of the plates 12 in their respective slots for a. purpose to be described.

In the plates12 are slots 15 lwhich over- .lap each other and are loosely 'pivoted together by the pivot member 16. 'These slots 15 are preferably arranged snbstantially at right angles to the axis of the shoe former as a whole.

Arranged at an angle to the axis -of'the shoe .former are slots 17 which are connected to alongitudinally movable member 18 by pins V19 'which loosely sliderin the slots '17.

lt will be noted that the slots 17 are placed so thatthey occupy'a sharp anfrle relative to each other. Since when the longitudinally niovable member 18. moves,v the pins 19 maintain their relation to each other, it follows that the lplates 12 will .be forced apart or drawn together, depending upon which di.- rection the longitndinally movable member is moved relative to the complementary portions.

Pivotally connected to the longitndinal'ly n'iovablemember at 20 is a-toggle member 21 whichohas at its other end a thnmb piece 22 which latter -is used to operate'the 'toggle Adjacent the thnmb piece 22 is 'a pivot meinher 23 which passes through the toggle member 321 and also through the other toggle member 24-, the slide and the spring 26, the latter being` held in the slide 25 as shown in 3.* The pivot member 23 is provided withan extended portion at the outer end of which is the button 241. That portioniof the .i pivot member 23 which is normally held in the plane of the toggle member 24: by 'the spring' 2G, is cylindrical in cross section While the portion normally in the plane of the ton'z'le member 21 is fiattened as shown in Figi. ll. i

The toz'glc member 211 is provided with a series of pivot bearing's .27. shown in Fig. 3. These pivot bcarinnjs 27 are connected to- ;rether by slots 28 to provide for passage of the ftattened portion of the pivot member 23 already/described. That 'portion of the I slide 25 remote from the pivot member 23, is freely movable along the toggle member 24. VVhen it is desired to give a different length over-all to the shoe former, the button 24 isA pressed in against the spring 26 which forces the cylindrical portion of the pivot member out of the pivot bearing 27 which brings the flattened portion in line for registration with the slots 28. The toggle 24 may now be readily forced in either direction. Vhen the proper length is reached, the pivot member 23 is released The spring 26 will force it to place in the first pivot bearing with which it registers.

In using my shoe former, the toggle is placed in angular position and the shoe former inserted in the shoe. The thumb piece is then pressed downwardly to extend the toggle. This action, of course, forces the forward toggle member 21 in a. forward direction with a consequent driving forward of the longitudinally movable member 18.

Considering now Fig. 1, it may be noted that the pins 19 are to the rear of the pivots 14. For this reason the pressure on the members 12 will be to the rear of the pins v14. As a point is approached where the pressure will pass directly into the pivots 14, the plates 12 will turn on their pivots 14. At this point, the leverage, forcing the complementary portions 10, 10a away from each other, pivots the plates 12, swinging them to positions shown in Fig. 2. During this swinging movement of the plate 12, the pivot pin 19 follows a curved path relatively to the pins 14 until the plates 12 rest at the bottoms of their respective slots as shown in Fig. 2. A continued forward movement of the longitudinally movable member is carried out. During this movement, the angle, between the slots 17 of the respective plates 12, because of the change of position of the plates 12, is lessened, thus permitting a greater movement of the longitudinally movable member for a given outward movement of the complementary members 10, 10a.4 The pressure outwardly by these complementary i members will consequently be greater during this latter part-of the stroke. This is, of course, what is desired.

It is clear that to release thetoggle and the complementary members, it is only necessary to lift the thumb member 22.

What 1 have shown and described an embodiment of my invention in detail, I desire to have it understood that the showing is merely illustrative and that modifications and changes may be made without departing from the spirit of my invention and within the scope of the appended claims.
